Multi-cyclone dust separator

Abstract

A multi-cyclone dust separator according to an embodiment of the present invention comprises a first cyclone unit having a first cyclone chamber and a first dust receptacle enclosing a circumference of the first cyclone chamber; and a second cyclone unit disposed below the first cyclone unit and having a plurality of second cyclone chambers and a second dust receptacle disposed under the second cyclone chambers to collect dust.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Provisional Application No. 60 / 666,144 filed on Mar. 29, 2005 in the United States Patent and Trademark Office, and Korean Patent Application No. 2005-37548 filed on May 4, 2005 in the Korean Intellectual Property Office, the entire disclosures of which are incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a multi-cyclone dust separator. [0004] 2. Description of the Related Art [0005] Generally, a cyclone dust separator separates dust and dirt from air using a centrifugal force and then discharges the air to the outside while collecting the dust and dirt in a dedicated dust collecting chamber. Such a cyclone dust separator is nowadays widespread since it is nearly permanent, whereas a conventional dust bag has a relatively short lifespan. In order to enhance dust suction efficiency of the cyclone dust separator...

AI Technical Summary

Benefits of technology

[0008] An aspect of the present invention is to solve at least the above problems and / or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present invention is to provide a multi-cyclone dust separator in which the number of second cyclone chambers can be increased in the same volume or circumference as a first cyclone chamber, thereby being improved in dust-suction efficiency.

Problems solved by technology

Such a cyclone dust separator is nowadays widespread since it is nearly permanent, whereas a conventional dust bag has a relatively short lifespan.

However, according to the conventional multi-cyclone dust separator by the present applicant, since an air induction path that guides the air into the first cyclone chamber is formed necessarily through the circumference of the first cyclone chamber, the second cyclone chambers formed on the circumference of the first cyclone chamber cannot be overlappingly formed with the air induction path.

That is, the second cyclone chambers can be formed in the rest space after forming the air induction path and therefore, increase in the number or volume of the second cyclone chambers, for better suction efficiency, is restricted.
